Description
【発明の詳細な説明】 本発明は、長尺接地電極材の銅条、又は、線材を現在地
盤から差のある将来整地地盤に対して使用できる如く地
中深く大深度に埋設する工法に関わる。The present invention relates to a method of burying a copper strip of a long ground electrode material or a wire material in a deep ground and a large depth in the ground so that it can be used for ground grading ground where there is a difference from the current ground. .
第１図のように将来整地される地盤２が現在地盤１よ
り、その差が６のような場合、現在盤より掘孔した掘孔
（接地電極材挿入孔）８に、接地電極材３の上端部４に
吊り下げ用線材としての細線５等を取り付け、接地電極
材３に祐度長さ７を設定して吊り下げる如くして挿入
し、土砂９によって埋め戻しする。When the ground 2 to be ground leveled in the future as shown in FIG. 1 is more than the current ground 1 and the difference is 6, the ground electrode material 3 is placed in the hole (ground electrode material insertion hole) 8 drilled from the current ground. A thin wire 5 or the like as a suspending wire is attached to the upper end portion 4, and the ground electrode material 3 is inserted so as to be suspended by setting a flexibility length 7 and backfilled with earth and sand 9.
ここで、掘孔８の長さは、切り削り地盤高差６と接地電
極材３の長さとを加えた長さにほぼ等しい。Here, the length of the dug hole 8 is approximately equal to the sum of the ground height difference 6 by cutting and the length of the ground electrode material 3.
埋め戻し後、将来地盤２迄ブルドーザー等のような土木
機械で第２図のように整地する場合、細吊り下げ部分
や、接地電極材３の上端部４は整地工事過程で諸外力に
よって切断される。After backfilling, when ground leveling up to the ground level 2 in the future with a civil engineering machine such as a bulldozer as shown in FIG. It
接地電極材３の祐度長さ７の部分のみ、整地後地表に残
り、その部分端は目視探査、測量探査等の手段によって
探索することができる。Only the part of the ground electrode material 3 having the length of about 7 is left on the ground surface after leveling, and the end of the part can be searched by means such as visual inspection or surveying.
地中の埋戻し部分は、埋戻し土砂等充填材の自然土圧に
よって埋戻しされているので沈下することなく、将来地
盤２に接地電極材３の上端部４が位置し、整地後に導線
（前記細線と同様に符号５にて示す）を接続すると簡単
に接地電極を形成することができる。Since the backfill portion in the ground is backfilled by the natural earth pressure of the filler such as backfill earth and sand, the upper end portion 4 of the ground electrode material 3 will be located on the ground 2 in the future and the conductor wire ( The ground electrode can be easily formed by connecting (indicated by reference numeral 5) like the thin wire.
